DEVICE FOR LEVELENG AND ALiGNlNG SHAFTENG.

SPECIE'ICATiON forming part of Letters Patent No. 318,886,6lated May 26,1885.

Application filed March 10, 1885. (No model.)

To aZZ whom it may concern:

Be it known that 1, CHARLES ESPENSOHIED, of Hastings, in the county ofDakota and State of Minnesota, have invented certain new and usefulImprovements in Leveling and Aligning Shafts; and I do hereby declarethat the following is a full, clear, and exactdescription thereof,reference being had to the accompanying drawings, and to the letters ofreference marked thereomwhich form part of this speciiication.

Figure l. is a front elevation of my invention. Fig. 2 is a plan viewshowing the same in operation. Fig. 31s afront elevation showing thesame in posit-ion for aligning.

The invention relates to improvements in mechanism adapted to ascertainthe departure of shafting from level or alignment, its object being toprovide means whereby such departure can be quickly and readilydiscovered; and it consists in the construction and combination of twoor more similar shaft-clamping devices, hereinafter described, andpointed out in the appended claims.

Referring to the accompanying drawings by letter, A represents aclamping device composed of the body-plate B, hinged or pivotedclamping-bar O, and clamping-screw D, as shown. The body-plate B isprovided with the rectilinear edges B B, at right angles to each other,and respectively provided with the levels Z) I). The edge of the deviceopposite the edge B is cut away to form the arms E E, parallel to theedge B and to each other, and the rectilinear edges 13 F, which run atopposite angles of forty-five degrees with the edge 15, and form witheach other the re entering rightangle f. approximating the edge 13*. Thearms E E and edges F 13 form between thcin the recess Z.

G is a centering-mark on the body-plate, which mark runs from the edge13, at right angles thereto, to the angle f, in the line bisecting thesaid angle. The clamping-bar O is hinged or pivoted at one end,c, on theend of the arm E, or in a recess therein, and has its outer end passingintoa recess in the end of the arm E, where it is retaincchwhennecessary, by the pin a, which passes through proper openings in theends of the bar and arm.

c is atra-nsverse threaded opening in the bar 0, which opening engagesthe clamping-screw D, which is provided on its outer end with a properhandle, (I, and on its inner end with a clamping-foot, d, to bear whenthe device is attached thereto.

H is a graduated glass tube secured to the body-plate perpendicularly tothe edge B. The said. tube is open above and below, and has coupled toits lower end arubber tube, it. The tubes H and h. are for levelingpurposes,as hereinafter explained, but form no part of the invention,asthe leveling can be done by any of the ordinary methods. The edgeXof thebodyplate is parallel to the edge 13, and the screw D, opening 0*,anglef, and centering-mark G are midway between said edges. While thisis not essentially necessary, itis better in practice.

To level a shaft one of the described devices is clamped thereon neareach of its bearings, and the edges B B of all brought horizontal by thelevels I) I). The said edges are then all vertically equidistant fromcenter of the shaft, and the necessary leveling, if any is required, canbe given by using a straight-edge with a spirit-level attached andleveling from thetop edge of one device to that of the adjacent one. Ifobstructions intervene,the graduated glasses H H and tubes h 71, allrunning to the same source of water-supply, can be used. I The saidglasses and tubes form part of my former application for patent.

In aligning, the devices are clamped on the shaft and the edges B"brought horizontal by the levels If. The centering-marks G G will thenbe vertically over the axis of the shaft, and the aligning can be donefrom a cord stretched between said marks, or between points equallyabove or to one side of the same, when obstructions intervene.

Having described my invention what I claim 1. In mechanism to discoverthe departure from level of shafting, a clamping device pro vided with arectilinear edge having a level attached to bring ithorizontal,arecess,Z,having a right angle, f, the bisecting line of which isparallel to the rectilinear edge of the clamping device, and aclamping-screw adapted to bind the shaft against the edges F F ofthereccss Z, with its axis in the same horizontal against the shaft Y Iplane as the bisecting line of the anglef, substantially as specified.

2. In mechanism to discover the departure from alignment of shafting, aclamping device provided with arectilinearedgehavingalevel attached tobring it l10rizontal,arecess, Z, having a right angle, f, the bisectingline of which is perpendicular to the rectilinear edge of the device, acentering-mark made on the extension of the said bisectingline, and aclamping-screw adapted to bind the shaft against the edges F Fof therecess Z,with its axis passing through the vertical plane in which thecentering-mark lies, substantially as specified.

3. In mechanism to ascertain the departure from level of shafting, thecombination of two or more clamping devices, A, each composed of thebody plate B, clamping bar 0, and

In testimony that I claim the foregoing as my 0 i own I affis: mysignature in presence of two witnesses.
